Combine the strawberries, lemon juice, and granulated sugar in a medium bowl. Set them aside to macerate for at least 15 minutes (but no longer than 1 hour).
While the fruit macerates, combine the strawberry jam and water in a small microwave-safe bowl. Microwave until warm, about 45 seconds. Whisk to combine. Set aside until ready to use.
¼ cup strawberry jam, 2 tablespoons water
In a trifle bowl or individual cups: place down a layer of angel food cake cubes, top with a layer of whipped cream, drizzle on the sauce, and finish off with a layer of strawberries. Continue layering until all the components are used or the dish is filled.
20 ounces angel food cake, 4 cups whipped topping
Notes
*Fresh strawberries work best and really make this dessert shine. Frozen berries tend to make this dessert soggy.**I use a tub of Cool Whip. Stabilized whipped topping works best here because it holds up well and doesn't weep. But if you prefer, you can use a homemade whipped cream, or Reddi-wip.***I use a store-bought cake when I'm short on time, but a homemade cake can be used instead. You can also use pound cake.Tips:
Macerating is similar to marinating. Fruit can be macerated by soaking it in a mixture of sugar and liqueur or fruit juice. The mixture is then set aside to soften and release its natural juices.
Serve this trifle in one big dish or in individual trifle cups.
Storage: Store strawberry shortcake trifle in an airtight container in the refrigerator for up to 2 days.
